CFBDSIR J145829+101343 b
CFBDSIR J145829+101343 b is a cold gas giant orbiting CFBDSIR J145829+101343 in the constellation Boötes. It lies about 75 light-years from Earth and was discovered in 2011 using the imaging method.
Is CFBDSIR J145829+101343 b in the Habitable Zone?
The position of CFBDSIR J145829+101343 b relative to the habitable zone of CFBDSIR J145829+101343 cannot be precisely determined from the available orbital data.
Temperature on CFBDSIR J145829+101343 b
The equilibrium temperature of CFBDSIR J145829+101343 b is about 370 K (97 °C) — hotter than anywhere on Earth. This estimate ignores any atmosphere, which could change surface temperatures dramatically — Earth's greenhouse effect adds about 33 °C.
Orbit and Year Length
A year on CFBDSIR J145829+101343 b — one full orbit around CFBDSIR J145829+101343 — lasts 10,037.5 Earth days, longer than Jupiter's 12-year orbit. It orbits at an average distance of 2.600 AU.
How Was CFBDSIR J145829+101343 b Discovered?
CFBDSIR J145829+101343 b was discovered in 2011 using the imaging method, with observations from W. M. Keck Observatory.
Direct imaging captures actual pictures of a planet by blocking out the overwhelming glare of its host star. It works best for young, hot, massive planets on wide orbits.
How Far Away Is CFBDSIR J145829+101343 b?
CFBDSIR J145829+101343 b is 75.3 light-years (23.1 parsecs) from Earth. Light arriving here tonight left the planet around the year 1951. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 1,325,280 years to make the journey.
Earth Similarity Index
The Earth Similarity Index (ESI) scores how physically similar a planet is to Earth, from 0 to 1, based on radius, density, escape velocity and surface temperature. CFBDSIR J145829+101343 b scores 0.07, ranking #4,896 of 5,565 planets with a known ESI. For reference, Mars scores about 0.70.
